not making this work is a huge mistake. I may have to download the old version of firefox because of the loss of functionality. SO LAME! This was a must have addon.

I would not go with an older version of Firefox for long, there would be security patches you are missing out on. Better idea might be to jump to something like PaleMoon that does support "legacy" extensions.
